Synopsis
Issued at 316 am est Wed jan 23 2019
rain will continue through the morning with temperatures holding in
the mid 30s to low 40s. Colder air then returns tonight with a few
snow showers or freezing drizzle possible downwind of lake michigan.

Much colder air then arrives Thursday night with highs on Friday in
the single digits and wind chill values around 20 below zero.

Periodic snow showers will be possible through the weekend...

especially in the lake effect snow belts... But any accumulation
will be very light.

Short term (today and tonight)
issued at 316 am est Wed jan 23 2019
surface temps finally clawing their way above freezing everywhere
early this morning as impressive vort MAX and associated surface low
approach NW in. Precip rates and coverage peaking during the next 6
hours but will luckily fall as just rain and advisory will be
allowed to expire. Could still be a few slick spots on secondary
roads in our N NW but most roads should be just wet for the morning
commute. Also will be some areas of fog through the morning as
snowpack melts in spots and some minor flooding is possible in
typical low-lying poor-drainage areas. Best low level moisture
convergence exits around 15z with midlevel dry slot arriving
shortly thereafter and bringing a quick end to steady precip.

However... Cyclonic flow persists through much of the evening with
trough axis not passing until late tonight and this will maintain
low chance pops (particularly downwind of lake mi). Temps will
also drop quickly during the late afternoon so any precip that
does fall will be either light snow showers flurries or freezing
drizzle given some ice nucleation concerns in shallow moist layer.

Guidance has trended drier and there is a good chance that most
of the area will be dry by the time surface temps drop below
freezing. The exception will be in the N NW where some light
precip may continue through the evening and could cause some minor
issues to the late afternoon commute. Overnight lows dip back to
around 20f in steady caa... Though real cold blast arrives later
thu.

Long term (Thursday through Tuesday)
issued at 316 am est Wed jan 23 2019
arctic front still slated to arrive Thu evening with some light snow
showers. Little no accumulation expected but steep low level lapse
rates and modest gradient could support some gusty winds and reduced
visibilities in any snow showers that do occur during the evening
commute. 850mb temps then plummet to around -24c across our north
for fri. Highs will once again struggle to get out of the single
digits. Fri morning lows will not be particularly cold in an
absolute sense given wind and clouds but wind chill values will
easily be in advisory criteria and warning criteria of -25f not out
of the question.

This marks the beginning of an extended period of relatively busy
weather as several clipper systems move through the region with
light snow chances. Most are weak though will have to keep an eye
on Monday system with potentially some much better dynamics...

moisture... And possibly warm air concerns aloft. Still far too
early to discuss any details though. After a brief moderation
sun mon... Temps plummet again for middle end of next week.

Aviation (for the 06z tafs through 06z Wednesday night)
issued at 116 am est Wed jan 23 2019
freezing rain appears to have ended at both airports, but plenty
of rain still to come through the next 6 to 10 hours before
tapering off. Heavier rain pockets are causing lower CIGS vsbys
with ifr being seen at times, especially ksbn. Expect ifr CIGS at
settle in at both sites overnight into weds given moist boundary
layer and slow melting compacting of snow. Cold front will sweep
through this afternoon with potential for drizzle freezing drizzle
returning later afternoon into weds evening. No mention in tafs
for now.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
